New library for math...

... note the swap of target_link_libraries lines in src/CMakeLists.txt,
needed to build at least on macOS, becuase FFT.h must be looked up first in
lib-math, not in lib-src/twolame

Also making a dependency cycle of SampleFormat and Dither!  But we will tolerate
that within one small library.
